Type material. Holotype. Brazil: Santa Catarina (Garopada 28°01’36.2”S, 48°36’48.0”W), 12–15. III.2001, M.P. Barros leg., 1M (MCN 33781). Collected by pitfall-trap.

Etymology. The specific name is derived from the type locality.

Diagnosis. The male of Euryopis catarinensis n. sp. is similar to that of Euryopis camis (see Levi, 1963, fig. 19) but differs from this latter species by having the median apophysis more rounded with the posterior margin sclerotized, while the median apophysis is elongated in the later; by the different course of the ducts in the tegulum, medially positioned (Fig. 8D), while the spermatic duct is positioned basally in the E. camis (see Levi, 1963, fig. 19).
